Raffiniert: Haase-Kellertank im Fachmagazin für den Wärmemarkt

Light liquid separators are used to treat mineral oil-containing wastewater or as retention devices and thus prevent mineral oils from getting into drainage systems.
The Haase light liquid separators are characterized by their special container. Due to the combination of glass fiber reinforced plastic (GRP) and polymer concrete, the separators are permanently resistant to chemicals and can withstand high static loads.
THE APPLICATION AREAS OF THE LIGHT LIQUID SEPARATOR
Light liquid separators are prescribed in companies where large quantities of oil or petrol are stored or can escape, e.g.
GAS STATIONS
WASHING STATIONS
WORKSHOPS
PARKING AREAS
Further areas of application: scrap yards, car dealerships, transfer stations, freight forwarders, building yards, fire stations
THE ADVANTAGES OF THE HAASE LIGHT LIQUID SEPARATOR
Resistance
dimensionally stable, corrosion-free and chemically permanently resistant thanks to the material GRP
Tightness
Dome shaft and pipe connections are factory-made on the tank, so there are no joints
Installation
also possible in cohesive clay soils and in groundwater, without complex substructure or foundation
Weight
Short installation times due to the low weight, enables moving without a heavy-duty crane
Entry
through the DN 1,000 manhole, without having to disassemble individual components
No follow-up costs
due to peeling coating or leaky joints in the shaft structure
Stability
Thanks to special polymer concrete, loads of up to 60 tons and inlet depths of over 4m can be achieved
Flexibility
Seamless dome shaft extension for realizing large installation depths and adjustable top section for variable adaptation to the top edge of the site
Compact
Sludge trap and coalescence separator are in one tank
Cleaning
due to the spherical shape, the separators have no edges on which dirt can stick
HOW OUR LIGHT LIQUID SEPARATORS WORK
Oil or gasoline separators (class II) The class II separator separates the separable substances from the calmed waste water purely physically on the basis of the principle of gravity. Oil and petrol collect on the water surface due to their lower density, solids such as sand and mud sink to the bottom due to their specifically higher weight.
Coalescence separator (class I) In the class I separator, the smallest drops of oil and petrol are brought together to form large droplets, which rise more easily and can therefore be retained better.
Automatic closure The automatic closure consists of a float that has a higher density than oil but a lower density than water. The float is thus between the water surface and the separated light liquid and closes the separator when the maximum storage volume is reached.
Consistent cleaning performance and low-maintenance operation thanks to filterless coalescence up to NS15
Checking
Quick and easy without having to disassemble built-in parts
Coalescence separator (class I) according to DIN EN 858-1 and DIN 1999-100 / 101 with general building inspectorate approval Z-54.3-537
Simple and robust for minimal effort
The LPA combines the sludge trap, coalescence separator and optionally the sampling point in one compact tank. The spherical shape of the container results in optimal flow guidance, which means that the coalescence insert up to nominal size 15 is filterless. This and the automatic closure on the drain, which is protected in the guide tube, reduces maintenance to a minimum. The clear structure and the easily accessible built-in parts make it easy for every operator and inspector to check the system.
Mechanical safety against light liquid escaping without being raised
Gasoline and coalescence separators
Density-independent nominal size calculation
Gasoline and coalescence separators (class II – I) according to DIN EN 858-1 and DIN 1999-100 / 101 with general building inspectorate approval Z-54.3-498
Effective and safe without the risk of jamming
The LPZ combines the sludge trap, petrol and coalescence separator and optionally the sampling point in one compact tank. The two separator classes II and I make it possible to reduce the nominal size by the density factor 1. In addition, the automatic closure at the inlet of the separator prevents the system from being backed up when the maximum oil storage capacity is reached, so that no light fluid can escape from the manhole cover if it continues to flow.

QUALITY PAYS OFF!
Every joint has a weak point! Refurbishments are often not permanent and are also expensive. Concrete separators are delivered in individual parts (base body, ceiling slab / cone and manhole rings) and assembled on site – in contrast to separators made of glass fiber reinforced plastic.
THE HAASE SEPARATOR
… is a seamless unit thanks to the unique combination of the material GRP with the spherical shape. The dome shaft is laminated directly to the tank body in the production process and can be adjusted as required depending on the installation depth of the separator.
The Haase separator has a three-layer structure, and between the GRP walls there is a filling layer made of synthetic resin-bonded pebbles.
This construction ensures the permanent tightness of the container, both from the inside and from the outside. Thanks to this unique wall structure, the GRP separator combines the chemical resistance of plastic with the stability of concrete.
THE KEY TO SUCCESS
… are the operating costs running towards zero. With Haase separators, the entire three-layer structure is made of one type of resin, resulting in a compact unit.
Concrete, on the other hand, has to be protected by a coating or an inliner. However, coatings wear out over time and inliners are only introduced into the basic container, the shaft area usually remains unprotected. This results in renovation costs in the course of the operating years, which together with the purchase price significantly exceed the costs of a GRP separator.
